Abstract: 829,595. Lighting burners. OATLEY TECHNICAL DEVELOPMENTS Ltd. July 4, 1958 [July 5, 1957], No. 21283/57. Class 75(3) A gas burner ring has a cover plate 13 spaced slightly above the top so as to provide a flash chamber 11 into which gas passes by a bleed opening 14 to be fired by an electric igniting element 15 with the flash passing through the circumferential opening 12 existing beneath the periphery of the cover plate to ignite all the jets 5 of the ring. The burner head is formed in two parts, the upper part 4 being provided with the jets 5 and having a depending cylinder 6 which engages a seating around a central aperture in the lower part 7 whereby the cylinder forms a central air passageway 8 at the top of which the electric igniting element 15 is mounted to project into the flash chamber 11. The igniting element is switched on just before the burner is to be used and remains in action; it can be energized from a battery or from the mains by a transformer. The cover plate 13 may have a central vent aperture covered by a spaced cap.

Title: Process for dyeing polyurethane foam
Inventor: WOOD JOHN FRANCIS
IPC: D06P3/24
Filed: 1957-07-05
Abstract: Polymethane foams are dyed by impregnation with an aqueous solution or dispersion of a dyestuff, the volume of the liquid being between 75 and 100% of the volume of the airspace in the foam.  The foam is uniformly dyed.  The impregnation may be assisted by squeezing and/or evacuation.  Dyestuffs referred to and used in the examples are Duranol Red GN, Carbolan Blue B, Coornassie Fast Green GN, and Dispersol Fast Yellow.  The polymethane foams used in the examples are derived from tolylene diisocyanate, water and (1) and (2), polydiethylene adipate; (3) polytetramethyleneglycol; (4) polyethylene glycol.  The dyestuff liquors may contain wetting agents.  After impregnation the dyed polymethanes may be heated at from 80-100 DEG  C. for 15-60 minutes, washed with water and dried.

Class 86 In a method of forming a dispersion of a finely divided solid in a liquid, a rotary stirring device operates continuously in in a container having filling and withdrawing means operated alternately at spaced intervals. The apparatus is particularly suitable for mixing paint and in one form described a container 1 supplies the partially mixed ingredients through a pump 2 to the bottom of the mixing container 4, which is partially filled with steatite beads. Discs 9, 9 on a motor shaft 7 are continuously rotated and perform a centrifuging action so that the mixture is thrown up the sides of the container and around one or more stationary baffles 9a. After a predetermined mixing time the emptying pump 13 removes the product through a screen 10 which prevents the passage of the steatite particles. Thereafter, the filling pump 2 feeds in a fresh charge of the materials and is automatically switched off when the contents in the container 4 reach a paddle 15 which actuates a switch 15a. The motor 8, driving the discs 9 is kept running continuously and the switching of the motors 13 and 2 is performed by automatic timing switches. Specification 850,687 is referred to.
